Chemical Structure
Description
Based on its molecular formula C36H66N2O2, (<I>R,R</I>)-(-)-<I>N,N′</I>-bis(3,5-di-tert-butylsalicylidene)-1,2- Cyclohexanediamine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 558.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
